JOHN R. ALLEN, OF PITTSBURG, PENNSYLVANIA:

IMPRovEMENT IN CARBURETERS.

Specification forming part of Letters Patent No. 165,050, dated J une29, 1875; application filed May 31, 1875.

To all whom it may concern: l

Be it known that I, JOHN R. ALLEN, of Pittsburg, in t-he county ofAllegheny and in the State of Pennsylvania, have invented certain newand useful Improvements in Carbureters 5 and do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings and to the letters of referencemarked thereon', making a part of this specitication.

This invention relates to certain improvements in apparatus forcarburetin g air or gas for the purpose of illumination, its objectheing to thoroughly and uniformly charge the air or gas with the vapor'of the hydrocarbon liquids, such as naphtha, benzine` Ste., in suchmanner as to produce, when burnt, a brilliant and steady iiame.

M y invention consists in an open-mouthed vessel formed of twoconcentric cylinders united to a common bottom, leaving an annular spacebetween the two for containing water, in which annular space an ordinarygasholder is set. rlhe inner cylinder is constructed with a daringmouth, and forms the carbureting-chamber of the apparatus, as fullyhereinafter set forth.

rlhe drawing represen ts a sectional view of my improved carbureter.

The letters A and B represent two concentric cylinders, of sheet metalor other suitable material, securely attached to the bottom O. Thecylinder B is constructed somewhat less in diameter than the cylinder A,so as to leave an annular chamber or space between the walls of the two,in which is set, mouth downward, an ordinary gas-holder, D, the annularspace being iilled, or partly filled, with water, to seal the mouthofthe gas-holder. The inner cylinder B is constructed with a flaringniouth, B', the object of which is to prevent any hydrocarbon liquidfrom being carried over into the annular chamber between the twocylinders, and thus prevents waste. Near the bottom of the inner chamberis arranged a box or chamber, E, of cylindrical or other suitable shape,having a foraminous or perforated bottom. Said box is secured to the endof the air or gas supplytube F, which enters at the center of theapparatus, projecting upward therein, and being provided with ascrew-thread, upon which the lower end of the tube G, which passes upthrough the bottom of the box E, may be seterminating near its top,serving to hold the box in proper position, and also to distribute theair or gas upon the top of the box, by which it will be deflectedandthrown downward uniformly through the perforations and thehydrocarbon liquid contained in the inner chamber of the apparatus. Tothe top of the boxE is attached a handle, Il, by means of which it canbe secured in the apparatus or removed at pleasure.

The air-supply pipe F extends upward on the outside to a height abovethe level of the hydrocarbon liquid in the inner chamber ot' theapparatus, and is connected with any suitable blast apparatus orgas-holder.

Said pipe may also serve to introduce the hydrocarbon liquid to theapparatus, in which case it is provided with a funnel and stopcock atits upper end, the blast or gas. pipe being tapped into its side belowsaid funnel.

rlhis will be found the most convenient arrangement for filling orcharging the carbureter with hydrocarbon liquid, although it may bedispensed with and the hydrocarbon introduced by removing thegas-holder.

The exit or escape pipe for the carbureted air or gas is represented bythe letter I, and extends downward from the top, or a point near thetop, of the o utercylinder, through the bottom ofthe apparatus, and isconnected with the service-pipes leading to the burners.

The inner chamber, or carbureting-chainber, being surrounded with waterwith which the annular chamber is filled, will be thereby rendered safeagainst lire, and all danger of explosions avoided.

l'he operation of the apparatus will be fully understood without furtherexplanation.

Having thus described my invention, what I claim, and desire to secureby Letters Patl ent, is-

The carburet-ing-chamber B, provided with an open iiaring mouth, B', toprevent the escape of hydrocarbon liquid, in combination with outerchamber A,4 forming an intervening annular watcrspace', as and for thepurposes set forth.

In testimony that -I claim the foregoing I have hereunto set my handthis 22d day of May, 1875.
